Muskrat Falls was a natural 15-metre (49 ft) waterfall located on the Churchill River about 25 kilometres (16 mi) west of Happy Valley-Goose Bay, Labrador.
The hydropower potential of Muskrat Falls was recognized in the early 1900s when the Grand River Pulp and Lumber Company proposed to build a dam along with a paper mill.
The site was developed as part of the Lower Churchill Project, despite concerns of methylmercury poisoning by researchers and local Inuit.
[citation needed] The rumour inspired a novel by Walter Sellars, Hard Aground published in 1992,[4] but was thought to be unsupported.
In 2010, coast guards searching for three men who died after being carried over Muskrat Falls found a 30-metre-long (98 ft) object on the bottom of the Churchill River, believed by diver Brian Corbin to be the missing U-boat.
